The Nike Free 5.0 Flash shoe's everyday Flexibility New hexagonal flex grooves are hot-knife cut into the outsole and wrap around the sidewall, allowing your foot to move more naturally in every direction.

Support and Breathability The knit mesh upper is reinforced with Flywire on the midfoot for lightweight ventilation and an adaptive, supportive fit that moves with you. Natural Stride The heel mimics the shape of your foot, rolling with the ground to promote a more natural footstrike.

8MM Offset With an 8mm difference between heel and forefoot height, the Nike Free 5.0 offers the highest offset of Nike Free running shoes for greater cushioning with the foot-strengthening benefits of natural motion.
